A brief tornado formed between Emden and Hartsburg, as the parent thunderstorm moved southeast. This tornado resulted in only minor tree and power line damage. It lasted only 3 minutes, touching down at 8:22 PM and lifting around 8:25 PM. It was seen by several spotters. The intensity ranking was F0, with winds around 70 mph.
A second tornado developed around 8:28 PM, and dissipated around 8:33 PM. This tornado touched down 3 miles north of Lincoln, and was seen by spotters as well as from the NWS office. The intensity ranking was F0, with winds around 70 mph.
The third tornado touched down about 5 miles north of Lincoln, again observed by NWS staff. It moved southeast, crossing I-55 near Lawndale. It crossed the Logan/De Witt County line about 3 miles east northeast of Beason, and lifted about 3/4 mile southwest of Hallsville around 8:51 PM. This tornado was rated as F1 intensity (100 mph) initially with a width of 400 yards. After crossing I-55, it strengthened to F2 intensity (130 mph), when it was about 1/2 mile wide. It weakened back to F1 intensity as it approached the De Witt County border (300 yards wide). This tornado traveled 14 miles, 11 of them in Logan County and 3 in De Witt County.
The fourth tornado touched down on the east side of Hallsville at 8:51 PM. It initially was 500 yards wide, and of F2 strength (120 mph). It grew to between 1/2 and 3/4 miles wide as it headed for Clinton. The tornado caused F2 damage (140 mph) as it moved across the south side of Clinton, destroying several businesses and causing damage to a few dozen buildings.
